<font face="Arial">Common to have a lot of light from balloons for
movie sets and other needs. So, heat doesn't seem to be a
problem.<br>

<div dir="ltr" data-setdir="false">I have a project where we
plan to use a 5' dia, vinyl, inflatable earth. It has a
provision to illuminate it with a battery powered LED, that
gets inserted into a clear tube that runs through it.
However, a reviewer comments that they wish it were
brighter. So, I have significant doubts that it will be
bright enough for our needs.</div>

<div dir="ltr" data-setdir="false">I imagine I would want at
least 1,000 lumens of light. Ideally, it would be dimmable.
I just looked at what was available for under cabinet LEDs,
and found ones that would fit in that tube (I would put two
back-to-back), and have the lumens I want. But, none of the
120vAC ones are dimmable, and probably wouldn't dim nicely
at the low end if they did. I have a DMX to LED dimmer
system that will work 5 to 24 DC. So I decided to check out
the car work lights, that are hard-wired into the car. But,
I have doubts they will fit into the tube.</div>

<div dir="ltr" data-setdir="false">I am also a bit concerned
about heat. Being installed in the inflatable, sealed with
a vinyl tube around it, is going to reduce its cooling. So,
perhaps bare LED strips are the way to go. If needed, I
could perhaps wrap the LED strip around some metal tubing.
That will both act as a heat sink, and I can get airflow
through it, if I can find some old metal vacuum cleaner
tubing.<br>

<div dir="ltr" data-setdir="false">Another related concept is
to make my own inflatable shapes. But, use the fan-inflated
type that uses nylon fabric. Then, airbrush with some
transparent paint to add images and color. But, I have never
attempted this. I see all kinds of paints advertised as
transparent. But, will it stick to nylon?</div>
